SPECIFICATION forming part of Letters Patent No. 606,426, dated J' une 28, 1898. Application inea June 3,1897. sermmsasge. (remodel.)

To all whom it may concern..-

Be it known that I, CHARLES MCCURDY, a citizen of the United States,fre siding at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in a Combination- Lock for Umbrellas; and I do declare'the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to Which it appertains to make and use the same.

My invention relates to improvements in combination-locks for umbrellas and the like; and the object is to provide a simple and eff ective device for locking the umbrella-frame to the handle to prevent the same being raised by a person not in possession. of the combination.

T o this end the novelty consists in the construction, combination, and arrangement of the several parts of the same, as will be hereinafter more fully described,and particularly pointed out in the claim.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a perspective view of a section of an umbrella stick or handle With my improved combnation-lock fixed thereto. Fig. 2 is a longitudinal section of the same, showing the manner of unlocking one of the nibs on the end of the ribs `in place. Fig. 3 is a transverse section.

1 represents a sleeve fixed to the handle, and it is provided with a circumferential groove 2 contiguous to the annular flange 3.

on its upper end. 4 and 5 represent radial pins fixed in said sleeve in the same longitudinal plane, and they extend through alined slots 6 and 7 in an encompassing sleeve S, which slides freely on the sleeve 1, fixed to the handle, its motion being limited by the slots 6 and 7. i

9 represents an annular ring mounted on the sleeve 8 and arranged to rotate freely thereon. It is provided with an internal lon-` gitudinal slot 10,1Which when alined with the pin et will permit the sleeve 8 to slide on the sleeve 1; but at all other times the pin abuts against the shoulder 11 of said ring and prevents the movement of the sleeve. A corresponding ring 12 is mounted on the sleeve 8 lbelow the rst-mentionedring, and it is provided With an internal longitudinal slot 13, Whichlmay be alined With the pin 5to permit the longitudinal movement of the sleeve 8. At all other times the shoulder 14; of the latter ring forms a barrierfor the pin 5. These rings 9 and 12 are provided with the usual division marks, ,and the collar 15 of the sleeve 8 is likewise divided, so that when the proper division-lines on the rings are brought into alinement with the zero or unison mark on the collar 15 the slots 10 and 13 are alined and the sleeve 8 will slide on the sleeve `l.

The inner annular face of the collar 15 is provided with a groove 16, which encompasses the outer portion of thenibs on the outer end of the umbrella-ribs to lock them against the 'groove 2 in the sleeve 1, and when the encompassing sleeve 8 has slipped down, as shown in Fig. 3, the nibs of the ribs are all released and the umbrella may be raised. Although I have specifically described the lconstruction and relative arrangement of the changes or modifications may be made as,

clearly fall within the scope of my invention Without departing from the spirit thereof. AHavin g thus fully described my invention, What I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s An umbrella-lock comprising a fixed sleeve provided with an annular groove, in combination With an encompassing sleeve formed With a corresponding groove and having a longitudinal movementthereon, one or more rings rotatably mounted on said encompassing sleeve, and means substantially as described for locking or releasing said'encomi passing sleeve on the fixed sleeve, substantially as shown anddescribed. In testimony whereof I hereunto ailix my signature in presence of tWo Witnesses. CHARLES MCCURDY. Witnesses:
